How does an air conditioner blower motor work?
As explained in the HVAC Blower Motor Guide, an air conditioner blower motor and assembly is basically the fan inside the air conditioning system that forces the cooled air, via the AC cooling coil, through the vents and into the room space that is being conditioned.
Can a malfunctioning AC compressor cause a problem?
The heat of summer can be intense, and the worst thing that can happen is finding yourself with a malfunctioning HVAC compressor. A working AC will provide you with nice and cold air as opposed to bearing the brunt of warm, dry air. With how much the HVAC runs, something is bound to go wrong with its compressor.
Why is my air conditioner not blowing air?
If you have a belt driven blower motor fan and the fan is not blowing any air through the vents, then it is possible that the belt may have become worn over time, moved out of place or become damaged. You can check for this problem by listening to the AC unit when it is turned on.

How does a furnace blower fan assembly work?
An example furnace blower motor fan assembly shows the blower motor connected in center and held in place by the mounting bracket, surrounded by the blower fan wheel and air outflow duct assembly. You can see the color coded wiring and run capacitor coming from the motor. Note that different assemblies will vary.
Why is my air conditioner blower fan not working?
Like all moving parts and similar to stand alone fans, the blower motor and blower fan is susceptible to wear and tear, as well as damage, all of which could result in the air circulation being restricted, or possibly not working at all.
Other options include removing the air conditioner blower motor from the AC unit and checking the label on the actual blower motor. Write this part number down for easy reference.

When do you need a new blower motor?
If you are getting 120 volts to the motor and it is not starting then you have a blower motor problem and either need another new blower motor or a new blower motor run capacitor. If you are not getting voltage to the blower motor out of the control board then you probably need a new control board again.

Is the blower motor the same as the fan control AMP?
Our version (at least for the auto control AC) is the Y33. The metal housing looks different, but the circuit board is the same with the same value components. In short, the blower motor is mounted in series with the fan control amp. The auto AC regulates the fan control amp, which regulates the voltage to the blower motor.
Where can I buy a blower motor for my air conditioner?
